标题： China building energy consumption: definitions and measures from an operational perspective

摘要： 对中国建筑能耗（BEC）重要性的认识正在增加。 然而，值得讨论的是，采用全生命周期或运行阶段的定义来估算建筑能耗。 在现有各种评估方法的研究中，关于中国建筑能耗的数量问题仍未被理解。 为了解决BEC计算方面的争议，本文建立了一个适当的建筑能耗核算方法，以呈现中国BEC的现状，并为建筑能效奠定基础。 采用建筑运行能耗的概念，我们发现建筑能耗仅占中国最终总能耗的15% - 16%；相比之下，以前的计算通常在考虑建筑集中供热的情况下通过自上而下的方法进行了重复计算。 显示英文摘要

摘要： There is an increasing awareness of the significance of Chinese building energy consumption(BEC). However, something worth discussing is that estimate the building energy consumption adopting the definition of life cycle or operation. In the existing studies with various evaluation methods, the issue about the amount of energy consumed by China buildings has not been understood. In order to settle the disputes over the calculation of BEC, this paper establish an appropriate accounting method of building energy to present BEC situation in China and lay the foundation for building energy efficiency. Adopting the conception of building operational energy consumption, we find that the energy consumption of buildings just accounts for 15% - 16% of the final total energy consumption in China; by contrast, the previous calculations usually have double accounting through top-down approach if central heat-supply of buildings was given into additional consideration.
